A ncauo mminmmber 25,1907. Serial No. 408,688.

The invention relates generally to an .ap-

paratus for producing multiply material in gefther into s eet form, as inv whatisgenerally .terme'd double-faced corrugated paper strawboard and'tiie like. i

The invention consists in the novel construction of the apparatus, in the peculiar arrangement and-combinationof its parts,

which the lagers or plies are cemented to vand in various details of construction, as

more full hereinafter set. forth;

In the ra ingg,'-+Figure l is a side eleva tion of the apparatus; Fig. 2 is a plan View Figs. 3, a mears detached sectional views, in elevation and planof thepressi-ng mechanism; Figs, and are cross sections in 5 different planesthrough the feed and cutting 1 mechanism; Fig". 8 isa longitudinal section through the feed mechanism; Fig. 9, is a similar section taken centrally through the framework; Fig. lOisa plan view, partly in section, ==showing the drive mechanism; Fig. 11 is a view in elevation of partsof the timing-mechanism; 12 is a sectional view of the driving meansfor the feed mech-' anism; and Fig. .13 isa viewin elevation of parts of the timing mechanism.

For thepurpose of describing the inven; tion, the a paratus. has been sho n and-will be hereinafter described asdesigned for producing double-faced strawboard,jand for this purpose its eneral constructionfconsists of mechanism for feeding superimposed layers of strawboar'd, in means for applying adhes sive material intermediate the layers, mechanism for ap lying fluid, pressuretothe Coated aa rs or h P I TPQ$$ stemmi them together, and in a c'ut-ofimechanism P eferab y x ing tt rfo se er n he rmed mu t ply; sheets. as; th d ed ng hs The me ha sm e y em, p oy dlm app y e flu d 16 the strawboard is a pneumatic p ss, hutlit will be obvious fromthe follo description t a y me m y be than-1,1 i

particular advantages of the use of this form -of pressure being more fully hereinafterset forth.

Thepress comprises generally a bed 1 and y a platen 2 having a yielding or flexible pressing surface 3. As shown, the platen is in the form of a closed casing 4', the pressing surface 3 of which is a flexible diaphragm forming the casing bottom, and beneath which and the bed the plies of material are adaptedto pass. Communicating with the interior of the casing described is an air conduit 5, through which air from a suitable source of supply, as a blower 6, is forced Within the casing for the purpose of depressing the diaphragm. A valve 7 controls the admission of air within the press, and, consequently, the operation of the latter, and this valve (as hereinafter set forth) is intermittently operated alternately 'with the feed mechanism. 7 h

Any form of controlling means may be used for the air conduit, but I have preferably shown a valve of the slide type, having zusliding engagement with the air conduit and su1: pr.- rted upon an upright exhaust pipe 611011 at its top and havingcommunication laterally through a pipe 9 with the air pipe The slide valve is apertured, as at 10, and the parts are so arranged and proportioned that, as the valve is withdrawn from the position indicated in full lines in Fig. 3 topermit the entry of air within the press,

the exhaust pipe 10 will be closed so as tomaintain the desired pressure upon the multiplymaterial within the press, and, upon a rflifersul of the valve, the air supply will be cut oil? and the ressure within the press relieved bythe discharge of the air through the; exhaust.

To expedite the cementing of thelayers of strawboard, hot air is used in theoperation of pressing, and a drier 11 is also applied in operative relation to the bed 1, so that when the material passes through the press it is su'liiciently set to permit of its being cut into sheets of the desired length.

, I have shown in the drawings as the preferable form of drier a system of steam pipingIQ, and have constructed the bed with a chamber 13 thereinto receive the pipes, the lutterbcing mounted upon suitable supports 14;. The ends-of the pipes of the system, as shownin Fig. 5, proje'ct through and beyond permit a fluid pressure to" e applied-the l the bed 1, and are adapted to connect with The strawboard is drawn through the.

4 press by feed rollers (hereinafter described),

and is adapted to be coated with adhesive material just prior to its entryywithin the press. I have shown, as the preferable form of means for applying the adhesive, a bath 15, with a roll 16 mounted to dip within the bath during its rotation, a suitable support, as 17, on which the parts are mounted, and reels 18-and 19 for the strawboard. Upon the reel 18 a quantity of single-faced strawboard is shown, consisting of a plain layer of paper and acorrugated layer, the material passing beneath a roller 20 before passing over the adhesive roll 16, the roll 20 serving to hold the strawboard in contact with the roll 16 so.as to receive the proper amount of adhesive. Upon the reel 19.is a continuous sheet of plane strawboard, which is adapted to pass over a'roll 21 and beneath the single-faced strawboard prior to entering the ress. v

. The eed mechanism, as previously set forth, is in the form of corrugated feed rolls,three sets,25, 26 and 27, being employed,mounted in standards 28 upon a suitable framework 29. These rolls are operated by a drive mechanism, consisting of a driven sprocket I 30 loosely mounted upon a shaft 31 journaled in hearings in the framework 29, a drive connection between the rolls and the sprocket comprising a suitable gear train 3,2 between the rolls and a gear 33 fixed upon the shaft 31, and a clutch 34 forming a drive connection between the gear 33 and the sprocket.

"The feed is adapted to be operated inter mittently to allow of the action of the press in cementing the layers, and a timing mechanism (more fully hereinafter described) is employed, actuated by the main operating mechanism for determining the periodof the feeding operation.

Mounted upon the supporting frame 29 in suitable standards 36 is a cutter or knife 37,

pivotally connected to the standards in operative relation tothe rolls by links 38 and 39, as plainly shown inFig. 7.

The main operating mechanism. for driving the press and the other parts of the apparatus, with the exception of the feed, is mounted upon the support 29, the several shafts formin parts of the operating mechanism being ournaled in suitable bearings on said support. This mechanism comprises a n n drive shaft 40, carrying at one end a (have pulley 41, and atits opposite end a fixed gear 42,

43 is a (iountcrshaft carrying connected gears44 and 45 loosely mounted thereon, the gear 44 meshing with the 'drive gear 42 on shaft 40, and a fixed ear 46.

47 is a driven sha on which is loosely mounted connected gears 48 and 49,-the

former meshing with the gear 45 on shaft 43,a fixed gear 50 to which is secured a star-wheel 51, and a fixed gear 52 meshing gear 50 on shaft 47, and an annulus 56 fixed to the segmental gear and engaging the star- -wheel 51, the annulus being provided with a notch 57 in its periphery arranged opposite the segment teeth, as plainly shown in Fig. 11. In addition to the gears described, the shaft 53 also carries fixed thereto a cam wheel 58 forming part of the timing mechanism previously referred to, and a cam 59 having a camway 60 formed in one of its faces.

The connection between the press and the operating mechanism just described is formed by a pair of vertical levers 61 fixedly secured to a transverse shaft 62, mounted in depending bearings '63 upon the press-supporting frame 64, a transverse rod 65 connecting'the upper ends of said levers, and a pair of inwardly-extending rods 66 pivotally connected to the rod 65 and to the valve 7, as plainly shown in Fig. 1. One of the levers 61 is provided with an extension 67 extending into operative relation to the cam 59, and provided with an extension 68 which engages the camway 60, as plainly shown in Fig. 12.

The drive mechanism 'between the knife and the main operating mechanism comprises a crank 69 upon the end of the shaft 43, a link 70 pivoted to the link 39, and a crank rod 71 connecting the crank with the pivoted link 70, shown in Fig. 7.

The timing mechanism for the feed includes, in addition to the cam 58 described, a vertical bar 72, slotted longitudinally as at 73 and 74, and mounted upon the shafts 31 and 53, the shafts extending through the of the main operating mechanism, and at its upper end carries a cross bar 76 adapted to engage a pair of escapement wheels 77 fixed upon the shaft 31 upon opposite sides of the bar 72. A roller 78 projects from one side of the bar into engagement with the cam 58. p

The clutch 34, forming a connection between the driven sprocket 30 and the gear train for the rollers, comprises a section 34 fixed to the shaft 31, provided with a facing 34 of leather or other suitable material, a similar facin 34 upon the sprocket 30, and a hand-whee '34 upon a threaded extension 34 on the shaft 31, as plainly shown in Fig. 12. The members of the driven sprocket.

clutch are always in frictionahengagement, and the degree of frictional contact is determined by the hand-Wheel.

The roller 16 for applying the adhesive material to the paper is driven simultaneously with the feed mechanism by means of a sprocket chain 80 engaging a sprocket wheel 81 upon one end of the roller, and a similar sprocket wheel 82 upon the end of one of the. feed rolls, as plainly shown in Fig. 2. 1 v

In the operation of the apparatus, motion is imparted from the main drive shaft 40, through the gears described, to theshaft 53, which is continuously driven. Intermittent motion is imparted to shaft 47 through the agency of the segmental gear, and by the intermeshing gears 52 and 46 similar intermittent motion is transmitted to shaft 43, the intermittently operating gears being locked during the periods of rest by meansof the star-wheel and the annulus with which, it engages. The intermittent rotation of shaft 43 reciprocates the knife 37 at stated intervals, the cutter operating during the operation of the press. The rotation of cam 59 intermittently operates the levers 61 connected to the valve controlling the pneumatic press, and thus allows the fluid pressure to be applied intermittently to the paper or the material passing through the press. As the cam 58 rotates, it causes the bar 72 of the timing mechanism to rise and fall, thereby throwing the locking bar 76 out and into engagement with the escapement 77 periodically. The clutch members, as previously set forth, being always in .frictional contact, as soon" as the escapement is unlocked or released the feed rolls operate through the agency of the continuously One of said clutch members rotates independently of the other when the escapement is locked, and the timing means for the feed is adapted to permit the feed mechanism to operate subsequent to the operation of the press.

As the layers of material to be cemented together are drawn by the feed rolls into the press,the adhesive material being previouslyapplied intermediate the layers or plies,the yieldingpressing surface of the press platen bears against the paper with sufficient force to properly cement the plies together, and by reason of the flexibility of the platen the pressure is uniformly applied to all portions of the paper within the press regardless of any irregularities in the paper that may exist; further, any likelihood of injury to the paper that might result in bringing a hard surface,such as a plate or similar appliance,-in contact therewith is prevented through the use of afiexible diaphragm; also the heated air that is preferably used in the operation of pressing, in conjunction with the drier in the press bed,-

thoroughly dries the cemented layers, so that as the paper passes from the feed rolls it is in condition for storing or use.

The operation of the press will be obvious from its construction, air under pressure being admitted upon the movement of the slidin valve outwardly and the air supply cut oil, and the air in the press exhausted upon the reverse movement of the valve.

While I have shown as the preferable means of cementing the layers the application of air pressure, it will be understood that any fluid may be employed without in any manner departing from the spirit of my invention. I do not therefore desire to be limited to the particular mechanism shown and described, although I consider this the preferable form, especially in the production of strawboard of the character described.
